Visual Flight Feedback as a Determiner of Motor Response Recognition

Abstract

Over a series of knowledge of results (KR) learning trials of projecting a ball a criterion distance, the hypotheses were tested that withdrawal of visual feedback of the flight of the ball (flight feedback), would produce a decrement in response recognition but not recall. Sixty subjects formed three independent groups which had visual flight feedback withdrawn either early or late, while a control group had no vision throughout the 91 trials. The hypotheses were confirmed. Withdrawal of flight feedback had no effect on response recall, but significantly impaired response recognition both early and late in the KR learning trials.
